Cage silsesquioxane, denoted as POSS, is a representative organic-inorganic hybrid molecule. Although POSS has been generally employed to improve organic materials, POSS-based materials, which contain POSS as a main component, are rarely studied. This is because of high symmetry of POSS; 1) precise synthesis of bi-functional POSS is difficult due to the equivalent reactivity of the eight corners, and 2) optically transparent POSS-materials are hard to be fabricated due to high crystallinity of POSS. Recently, we have been working on the creation of POSS-based materials by “symmetry control” strategies. Incompletely-condensed POSS (IC-POSS), in which one of the eight corners is removed, is a key building block to reduce symmetry. We have reported single molecular materials, amphiphilic molecules, and, main-chain polymers by utilization of IC-POSS. In this presentation, the molecular designs and the properties of the resultant materials will be introduced. |
